MASSACHUSETTS, A CORPORATION OF MASSACHU- SHINGLE-S'IRIP.

Application filed April 19,

sheet of felt with pitch, asphalt or other waterproofing composition, coating it with a higher-melting-point pitch or asphalt and partially embedding in the coating a layer of grit or crushed slate or other mineral, to cut the sheet longitudinally and transversely into shingles of the desired length and width. The shingle-cutting machines function with great rapidity, and it has been necessary to employ a number of operators to gather the shingles and by hand to stack them in piles for packaging. The fact that a plurality of shingles are delivered simultaneously from the machine, and that a con-. stant stream thereof is discharged. with the liability of theindividual shingles to overlap and become askew, has rendered very diflicult the problem of providing some automatic mechanism for'stacking or piling the shingles for packing and shipment. Where the units delivered by the machine are equal to the width of the initial sheet, the problem is rendered more simple, and in a copending application, Serial No. 280,458, filed March 3, 1919, by James L. Hildebrand and Hans H. Wanders, a machineis shown for automatically stacking and piling, such units, which take the form of shingle slabs or shingle strips so-called.

The present invention consists in forming a strip comprising a plurality of shingles which are laterally connected by narrow webs so that they will be more easily stacked and piled, and so that they may be shipped in flat packages. The webs are so narrow that the shingles may be easily detached from each other when it is desired to place them on a roof.

On the accompanying drawing, Figure 1 represents more or less conventionally a machine which may be used in forming the strips of connected shingles.

Figs. 2 and 3 represent the slitting cutters which may be employed for forming the Specification of Letters Patent.

1919. Serial No. 291,400.

interrupted longitudinal slits in the sheet of roofing.

- Fig. 4. represents a strip of laterally connected but detachable shingles.

Any suitable or convenient form of machine may be utilized, but I have illustrated more or less conventionally a machine having the feed rolls 10, 10, and slitting cutters 11, 11, which are secured upon the shafts 12, 12. A plurality of pairs of slitting cutters are arranged upon the shafts so as to form a plurality of parallel interrupted slits or cuts in the sheet of roofing material. These pairs of cutters are spaced apart a distance equal to the desired width of the ultimate shingles. 14 indicates a chopping cutter which cooperates with a stationary blade 15 in severing the sheet transversely.

The slitting cutters 11, 11, are provided with registering notches 16 so that the slits or longitudinal cuts in the sheet are interrupted leaving narrow uncut webs, and the cutters are so adjusted upon the shafts 12 that the chopping cutter 14 will cut the sheet on lines intersecting the slits, as shown in .Fig. 4.

Any suitable power-transmitting mechanism may be utilized for effecting the operation of the chopping cutter, the slitting cutter and the feed roll, and I have shown conventionally a suitable form of powertransmitting mechanism which need not be described in detail as it is well known; in fact, except for the provision of the notches in the slitting cutters, the machine as illustrated does not differ from those which are now in use.

In Fig. 4 I have shown a strip of connected shingles as produced by the machine, and it will be observed that it consists of a plurality of shingles a connected at points between their ends by narrow uncut webs b. It is not necessary that the shingles should be connected by two webs as indicated, as a single web may be employed for connecting each pair of adjacent shingles. These webs, however, are so narrow (being scored if desired) that by bending the strip on the lines of the interrupted cuts, the individual shingles may be easily detached from each other. I regard it as more desirable to have the uncut webs located at points intermediate the ends of the shingles so that the corners thereof will be sharp, although I should not regard it as a departure from the invention if the shingles were connected at points immediately adjacent the ends thereof.

What I claim is 1- As a new article of manufacture, a strip of prepared roofing material formed of felt saturated with a bituminous compound and consisting of a plurality of shingles laterally severed from each other throughout the greater portion of their length, but connected by narrow Webs of uncut material.

In testimony whereof I have aflixed my signature.
